Patenwd Nova 22, 1921 A iys ig l 2 cool 3 where of large size chunkoriireiicr for mens shoes is shown ili'lfi body portion 1 is providedor: its comflr upper position ul'iowri is Fig: 7 is secured to thebodyporchion wiriili'ss rib 4 embedded in the groom r: wirliriic ficii;surface of the web I io rile surface of ihe body portion us shown in 2The reinforce is held iii piece by driving the pics 5 through the 000"portion and bending down rhus fir W securing; the reinforce in placewirhouis .ieeviiig unyprojecvions above fiche fiarfi upper surface ofiliifijsllllllii siiiener.

The construction iliuslzrclzecl iii 4 mil 5 is {similar to that jusztdescribed dept chef in Ellis case ijhe groove 3' in the bony portion 1corresponds in gene-rel cross seciion to the cross section of thereinforce so llmt when the reinforce secured in place the upper fiatsurface of the Web 3 not only c izforms to the upper surface of the bodyportion 1 bro; SllbSimlfiifiiliy coincides at Elie sides of the Web withthe upper surface of the web.

The form of shank stiffener shown in Fig. 6 may be constructed either asshown in Fig. 3 or 5. out in this case the reinforce 8 is brought downi; the very end of the body portion 9 as shown at the left, thusenabling the end of rho stiffener to be placed beneath fshe heel of aboot or shoe when the shank stiffener is in place to serve as a reiforccrnent which is pariiculcrly desirable when a Wooden lieel used orwhen extra amount of reinforcement for any reason desired Having fullydescribed. my invention, What; I claim as new and cleeirc igo secure byLei- Potent is:
